Those who run LPG converted 2.2's

Maybe. Now the Lpg times are greater are the Lpg mixtures ok? Try cleaning the maf?

I'll test for leaks and clean the maf while at it. Lpg mixture barely goes rich ever (0.97 lambda maximum) and is lean most of the time.

Hello i Am new here and i Am sorry for my bad English
But wen the presure raises in the Intake you get negatieve presure against te lpg injectors
Can that reduce lpg flow to te intake ?
Like petrol for each bar boost the fuel regulator raises 1 bar
Maybe i Am totaly wrong

The Lpg pressure also increases with boost like petrol does so no problems there.

Petrol seems to be on the rich side too now that I had a look. 3rd gear and it goes to 0.76 Lambda. PRJ have said in other thread anything less than 0.78 you loose power massively. So maybe that's why it's been messing with LPG too?

OK it's about the same now. Increased both points by 15% but still goes lean? Ms are about the same for both at the point where it stops.

[diesel des]

Yes both the 12.9 and the 14.3 points

So that would be the 12.9 point in #468 on page 32?

[diesel des]

Increase the part in your map with a point near 14ms on petrol and 12 on gas. Add 10% and test

Here is a video of the injector times. stops at 12ms and just doesn't increase.

I'll go out and check, then report back

[diesel des]

Yes Motronic times should be the same on Lpg and petrol.

I will go out tonight and get dad to see what happens with lpg times and petrol times, as they should be about the same shouldn't they?

[diesel des]

Yep. Has the Motronic reduced it pulse time?
